The previous refactoring of some code in tpacpi_dytc_profile_init() left
a weirdly indented code-block behind.
Remove the unnecessary '{}' and reduce the indent level one step,
other then changing the indentation the code is completely unchanged.

Remove the dytc_profile_available check from dytc_profile_set(),
that function only gets called if the platform_profile_handler was
registered, so the check is not necessary.
Make tpacpi_dytc_profile_init() return -ENODEV when it does not register
the platform_profile() handler this will cause
dytc_profile_driver_data.flags.init to not get set, which in turn will
cause the dytc_profile_exit() call to get skipped.
Together this avoids the need to have the dytc_profile_available
variable at all, since the information is now duplicated in the
dytc_profile_driver_data.flags.init flag.
Note this leaves a weirdly indented code-block behind, this is
deliberately done to make what actually changes in this commit clear.
This will be fixed-up in the next commit.

The only reason the proxysensor code needs dytc_version handling is for
proxsensor_attr_is_visible() and that will only ever get called after
all the subdrv init() callbacks have run.
tpacpi_dytc_profile_init() already calls DYTC_CMD_QUERY and is the
primary consumer of dytc_version, so simply let tpacpi_dytc_profile_init()
set dytc_version and remove the now no longer necessary dytc_get_version()
helper and its calls.

Make ibm_init_struct.init() callbacks return -ENODEV instead of 1 when
the subdevice / function is not available.
Using -ENODEV clearly states what it going on where as a magic return of
"1" requires a deep dive into the code to figure out what is going on.
This also allows for some cleanups, avoiding the need to translate an
-ENODEV return into "return 1" (which often mistakenly was "return 0").

Commit 79f960e29c ("platform/x86: thinkpad_acpi: Convert platform driver
to use dev_groups") accidentally modified tpacpi_kbdlang_init() causing it
to return -ENODEV instead of 0 on machines without kbdlang support
(which are most of them).
ibm_init() sees this -ENODEV as an error causing the entire module to not
load, not good.
Note that technically tpacpi_kbdlang_init() was already buggy before, it
should have returned 1 instead of 0 if the feature is not present.
Rather then fixing tpacpi_kbdlang_init() though, IMHO it is bettter to
just make ibm_init() treat -ENODEV as 1 to fix the issue; and then in
a followup commit also change all the existing "return 1"s from
ibm_init_struct.init() callbacks to "return -ENODEV" as -ENODEV clearly
states what it going on where as a magic return of "1" requires a deep
dive into the code to figure out what is going on.
This will also allow removing some extra ifs to translate -ENODEV to
return 1 in a couple of init() callbacks.

Add support for custom fan curves found on some ASUS ROG laptops.
These laptops have the ability to set a custom curve for the CPU
and GPU fans via two ACPI methods.
This patch adds two pwm<N> attributes to the hwmon sysfs,
pwm1 for CPU fan, pwm2 for GPU fan. Both are under the hwmon of the
name `asus_custom_fan_curve`. There is no safety check of the set
fan curves - this must be done in userspace.
The fans have settings [1,2,3] under pwm<N>_enable:
1. Enable and write settings out
2. Disable and use factory fan mode
3. Same as 2, additionally restoring default factory curve.
Use of 2 means that the curve the user has set is still stored and
won't be erased, but the laptop will be using its default auto-fan
mode. Re-enabling the manual mode then activates the curves again.
Notes:
- pwm<N>_enable = 0 is an invalid setting.
- pwm is actually a percentage and is scaled on writing to device.

When WWAN device wake from S3 deep, under thinkpad platform,
WWAN would be disabled. This disable status could be checked
by command 'nmcli r wwan' or 'rfkill list'.
Issue analysis as below:
When host resume from S3 deep, thinkpad_acpi driver would
call hotkey_resume() function. Finnaly, it will use
wan_get_status to check the current status of WWAN device.
During this resume progress, wan_get_status would always
return off even WWAN boot up completely.
In patch V2, Hans said 'sw_state should be unchanged
after a suspend/resume. It's better to drop the
tpacpi_rfk_update_swstate call all together from the
resume path'.
And it's confimed by Lenovo that GWAN is no longer
available from WHL generation because the design does not
match with current pin control.

Platform drivers have the option of having the platform core create and
remove any needed sysfs attribute files. So take advantage of that and
refactor the attributes management to avoid to register them "by hand".
Also, due to some attributes are optionals, refactor the code and move
the logic inside the "is_visible" callbacks of the attribute_group
structures.

A Lenovo ThinkStation S20 (4157CTO BIOS 60KT41AUS) fails to boot on
recent kernels including the think-lmi driver, due to the fact that
errors returned by the tlmi_analyze() function are ignored by
tlmi_probe(), where tlmi_sysfs_init() is called unconditionally.
This results in making use of an array of already freed, non-null
pointers and other uninitialized globals, causing all sorts of nasty
kobject and memory faults.
Make use of the analyze function return value, free a couple leaked
allocations, and remove the settings_count field, which is incremented
but never consumed.

Extend systems of class VMOD0010 equipped with CoffeeLake COMEx module
with BIOS related attributes to represent various BIOS statuses.
These attributes "bios_active_image", "bios_auth_fail",
"bios_upgrade_fail", "bios_safe_mode" has been already added to modular
system. This all of them are already documented.
- "bios_active_image" - location of current active BIOS image (0: Top,
1: Bottom. The reported value should correspond to value expected by
OS in case of BIOS safe mode is 0. This bit is related to Intel
top-swap feature of DualBios on the same flash.
- "bios_auth_fail": BIOS upgrade is failed because provided BIOS image
is not signed correctly.
- "bios_upgrade_fail" BIOS upgrade is failed by some reason not related
to authentication. For example, due to physical SPI flash problem.
- "bios_safe_mod": - 0 : if BIOS is booted from a supposed active image;
1 : BIOS safe mechanism was enforced by hardware (CPLD).

RTC based wakeup from s0i3 doesn't work properly on some Green Sardine
platforms. Because of this, a newer SMU for Green Sardine has the ability
to pass wakeup time as argument of the upper 16 bits of OS_HINT message.
With older firmware setting the timer value in OS_HINT will cause firmware
to reject the hint, so only run this path on:
1) Green Sardine
2) Minimum SMU FW
3) RTC alarm armed during s0i3 entry
Using this method has some limitations that the s0i3 wakeup will need to
be between 4 seconds and 18 hours, so check those boundary conditions as
well and abort the suspend if RTC is armed for too short or too long of a
duration.

Add a driver providing access to the GPIOs for the identify button and led
present on Barco P50 board, based on the pcengines-apuv2.c driver.
There is unfortunately no suitable ACPI entry for the EC communication
interface, so instead bind to boards with "P50" as their DMI product family
and hard code the I/O port number (0x299).
The driver also hooks up the leds-gpio and gpio-keys-polled drivers to the
GPIOs, so they are finally exposed as:
LED:
/sys/class/leds/identify
Button: (/proc/bus/input/devices)
I: Bus=0019 Vendor=0001 Product=0001 Version=0100
